Why should you add acid to water and not water to acid?

If you add water to acid, you form an extremely concentrated solution of acid initially and the solution may boil very violently, splashing concentrated acid. If you add acid to water, the solution that forms is very dilute and the small amount of heat released is not enough to vaporize and spatter it.

Why should one add acid to water rather than add water to acid when preparing solutions describe in 1/2 sentences?

Adding more acid releases more heat. If you add water to acid, you form an extremely concentrated solution of acid initially. So much heat is released that the solution may boil very violently, splashing concentrated acid out of the container! So Always Add Acid to water, and never the reverse.

What happens when an acid is added to water?

Adding water to an acid or base will change its pH. Water is mostly water molecules so adding water to an acid or base reduces the concentration of ions in the solution. When an acidic solution is diluted with water the concentration of H + ions decreases and the pH of the solution increases towards 7.

Why acid is added to water before electrolysis?

Water is a poor conductor of electrcity. Addition of a few drops of sulphuric acid (H2SO4) makes water conducting in nature because the acid ionises in water to release H+ ions and HSO-4 ions.

Why is adding acid to water exothermic?

When acid is poured into water, it flows down the flask and mixes much better, so no boiling occurs. So much heat is released that the solution may boil very violently, splashing concentrated acid out of the container and all this because the reaction is exothermic.

Why is it recommended that the acid should be added to water?

Answer: The reaction of acid and water is an exothermic reaction since a lot of heat is liberated during the reaction. This heat changes some water to steam explosively which can splash the acid on our face or clothes and cause acid burns. As a result, adding acid to water is safe, but adding water to acid is not.

What should be added to water during its electrolysis so that it can conduct electricity?

To carry out the so-called electrolysis of water, sulphuric acid is added to water.

Should you add acid to base or base to acid?

Adding an acid increases the concentration of H3O+ ions in the solution. Adding a base decreases the concentration of H3O+ ions in the solution. If a base is added to an acidic solution, the solution becomes less acidic and moves toward the middle of the pH scale. This is called neutralizing the acid.

Why does one always slowly add the acid to water?

Heat is generated After measuring out your concentrated acid and water, the acid must always be added to the water. This is because when the two mix, heat is generated – this is called the “Enthalpy of solution” or “enthalpy of dissolution”.

Why should you never pour water into a strong acid?

Pouring acid in large amount of water result in diluted solution with very less heat release. It generates more heat when u put water in acid and could break the apparatus so it is suggested that you do the reverse. A large amount of heat is released when strong acids are mixed with water. Adding more acid releases more heat.

Why should water never be added to concentrated acid?

Remember, you should never add water to acid. This is because the reaction is exothermic, and the solution may splash out. If you add water to acid, it will be acid which splash onto your skin and being concentrated, it is highly corrosive. Hence, you should always add acid to water slowly.

Why is acid always added to water, and not the reverse?

If you add acid to water, the solution that forms is very dilute and the small amount of heat released is not enough to vaporize and spatter it. So Always Add Acid to water, and never the reverse. read less
